While vegetables like kale and broccoli are nutritious, consuming them raw in large amounts can hinder thyroid hormone production. They contain goitrogens, compounds that may reduce iodine absorption—essential for healthy thyroid function.
Tip: Cooking cruciferous vegetables reduces their goitrogenic effects. Steaming or sautéing is recommended.
Examples: Raw cabbage, broccoli, kale, Brussels sprouts.
3. Gluten
For individuals with autoimmune thyroid diseases like Hashimoto’s, gluten can act as a trigger for inflammation and immune system flare-ups. It may also damage the gut lining, affecting nutrient absorption and medication effectiveness.
Tip: Consider a gluten-free diet if you experience persistent fatigue, digestive issues, or have been diagnosed with Hashimoto’s.
Examples: Wheat, barley, rye, processed oats.
4. Refined Sugar
Excess sugar causes inflammation, increases insulin resistance, and can worsen symptoms of hypothyroidism such as weight gain, mood swings, and brain fog.
Tip: Replace refined sugar with natural sweeteners like honey (in moderation) or fruits with a low glycemic index.
Examples: Candy, pastries, sugary drinks, packaged desserts.
5. Processed and High-Sodium Foods
